I should have mentioned that this applies to Linus' 3.13.0-rc7 and rc8 git. Maybe it's obvious. Sorry about that.

Greetings, After the modesetting commit, I have been unable to compile xf86-video-nouveau. The git site for drm given on the wiki page does not get the proper xf86drmMode.h, etc. I noted that libdrm git has over 100 branches and I really don't want to try all of them. Fedora 9 has a patch of the libdrm source rpm that includes an earlier version of xf86drmMode.h but it's now out of

https://bugs.freedesktop.org/show_bug.cgi?id=71455 --- Comment #2 from Bob Gleitsmann <rjgleits at bellsouth.net> --- Here is an additional data point. The problematic kernel sets 0xb20010f0 to 0x83ff03ff. The driver reports that the PWM is 100%. In fact it is 100% off. As can be expected, the temperature immediately begins repidly rising. Interestingly, the card seems to self protect by t...

https://bugs.freedesktop.org/show_bug.cgi?id=71455 --- Comment #3 from Bob Gleitsmann <rjgleits at bellsouth.net> --- The fan PWM setting is derived from priv->cstate. The value it gets from there is zero. So the setting of PWM for NV40 is working correctly, "inverting" the percent setting to get the value set in 0xb20010f0. Probably priv->cstate is never initialized. I'...

https://bugs.freedesktop.org/show_bug.cgi?id=71455 --- Comment #4 from Bob Gleitsmann <rjgleits at bellsouth.net> --- Oh, the value reported by the driver for the PWM setting is the value before it is set by the driver.

However, I will offer as a final remark that perfE.pstate = 0x20 on my card. It gets into nv40_clock_ctor but the fan speed is never set. According to nvbios, for this card the default setting for the fan speed i...

Hi, uevent support was added to the nouveau DDX in a recent commit. A test is made in configure.ac for libudev being present but there is no minimum version. I have had problems with this as I am using Fedora 11 which has udev-141 in it. This version does not support all of the functions required by the DDX and will crash Xorg. At least this function is missing:
